Abstract

A television data capture device is used with a television set or monitor to selectively extract, store, retrieve and display on the TV set or monitor extracted digital data. A composite video-digital signal is received from which digital data is removed by a digital data extractor. A memory unit, a permanent storage unit, and a microprocessor are also provided, enabling the user to store and retrieve from storage selected digital data previously extracted from the composite signal. A digital video converter converts extracted digital data to video signals for display of extracted digital data with the currently transmitted video signal.

Claims

1. A digital data capture apparatus used by a receiving party and capable of operating in combination with a TV set or monitor and an extraction circuit for extracting portions of digital data selected by said receiving party from a composite video-digital signal comprising:

receiving means for receiving said composite video-digital signal, said signal including video and digital data having no addresses associated therewith,

storage means for storing said portions of digital data under control of instructions directed to a microprocessor, said portions of digital data being selectively extracted from said composite signal under control of said receiving party,

memory means communications with said microprocessor for storing programs and said selected digital data, and

a microprocessor for receiving said selected digital data from said extraction circuit, said microprocessor communicating with said memory means and with said storage means for controlling the selected storage, retrieval, erasure and display of said selected digital data.

2. The apparatus of claim 1, further including display means for visually displaying selected digital data.

3. The apparatus of claim 2, wherein said display means is said TV set or monitor.

4. The apparatus of claim 1, further including a communication link between said extraction circuit and said TV set or monitor to enable the transmission of video signals from said composite signal to be continuously displayed on the screen of said TV set or monitor.

5. The apparatus of claim 1, where said composite video-digital signal is a broadcast signal.

6. A digital data capture device used by a receiving party and capable of operating in combination with a personal computer, comprising:

receiving means for receiving a composite video-digital signal,

means for delivering said composite video-digital signal to said personal computer,

an extraction circuit enabling said receiving party to extract selected portions of digital data from said composite video-digital signal,

storage means for storing said selected portions of digital data under control of instructions directed to a microprocessor,

memory means communicating with said microprocessor for storing programs and said selected portions of digital data, and a microprocessor for receiving said selected portions of digital data, said microprocessor communicating with said memory means and with said storage means for controlling the storage, retrieval, erasure and display of said selected portions of digital data.

7. The apparatus of claim 6, further including display means for presenting said selected portions of digital data.

8. A digital data capture apparatus used by a receiving party and capable of operating in combination with a TV set or monitor and an extraction means enabling said receiving party to select portions of digital data for extraction from a composite video-digital signal, comprising:

receiving means for receiving a composite video-digital signal, said signal having no addresses associated therewith for determining which receiving party should receive it,

processing means including a processor operating under control of a stored program and storage means for storing said selected portions of digital data, said processor enabling said receiving party to selectively store said portions of extracted digital data, retrieve said portions of digital data from storage, and display said portions of selected digital data.

9. The apparatus of claim 8, where said composite video-digital signal is a broadcast signal.

10. An apparatus for use by receiving party and capable of operating with a TV set or monitor, a receiving means for receiving a composite video-digital signal having no address associated with delivery thereof and an extraction means for enabling the receiving party to select any portion of digital data for extraction from said composite signal, said apparatus including:

storage means for storing said selected digital data under control of instructions directed to a microprocessor,

memory means communicating with said microprocessor for storing programs and said selected digital data, and

a microprocessor for receiving said selected digital data, said microprocessor communicating with said memory means and with said storage means for controlling the selective storage, retrieval, erasure and display of said selected portions of digital data.

11. The apparatus of claim 10, where said composite video-digital signal is a broadcast signal.

12. A digital data capture apparatus capable of use by a receiving party together with a TV set or monitor, a personal computer and a receiving means for receiving a composite video-digital signal having no addresses associated with it, said apparatus comprising:

an integrated circuit card having as a component therein an extraction circuit enabling said receiving party to extract selected portions of digital data from said composite signal,

storage means for storing said extracted digital data under control of instructions directed to a microprocessor, and

memory means communicating with a microprocessor for storing programs and said extracted digital data and a microprocessor for receiving said extracted digital data, said microprocessor communicating with said memory means and with said storage means for controlling the selected storage, retrieval, erasure and display of said selected portions of digital data.

13. The apparatus of claim 12, further including means for displaying said selected digital data on said TV set or monitor.
